Variations of beechnut traits and seedling heights in four European beech (Fagus sylvatica L.) populations in Croatia
In the autumn 2016 seeds were collected in four registered beech seed stands of Forest Administrations Ogulin, Bjelovar, Karlovac and Požega. In each population five trees were selected and seeds were collected below them in the interval from September to November. Random samples of 80 nuts per tree (400 nuts per population) were taken and their length, width and mass were measured. In the spring 2017 nursery test was established in the nursery of Croatian Forest Research Institute. Seeds were sowed in containers type Bosnaplast 18 of 220 cm3 volume and 1.617 seeds per tree have been sown. The containers were field with a PROFI MIX 1a substrate. I total, 32.340 seeds have been sown. Watering and protection of insolation were carried out regularly during the growing season. Measurement of one year old seedling heights was done in the spring 2018. All statistical analyses were done using the statistical programme STATISTICA 13.3. The inter- and intra- populations variability for the investigated variables were tested with univariate analysis of variance (ANOVA). The highest values of seed length, seed width and mass were identified in the Bjelovar population, while the lowest values of the observed characteristics were in the Požega population. Analysis of variance confirm statistically significant differences in a seed length, width and mass between populations. There were no statistical differences among populations for seedling height. The mean height was lowest in the Bjelovar population and highest in the Požega. Correlations between seed morphometric characteristics and seedling height were negative and statistically significant. These results should be regarded as preliminary assessment and a stimulus for further research of beech genetic variability in Croatia.
